POWER GENERATION CONTROLLER FOR VEHICLE

摘要

PURPOSE:To prevent mixing of noise to a radio and flickering of head lamp by perfectly eliminating surge and impulse of power supply voltage generated by duty control of a field current. CONSTITUTION:A power generation controller for vehicle comprises a microcomputer 10 for computing an instruction value of a field current flowing into a field coil 2 of a power generator from a detected voltage of a battery 7 and a preset value of output voltage of a power generator 1A for vehicle and a field current control circuit 9 which can continuously change a field current based on the instruction value from the microcomputer and a feedback value of the actual field current flowing into the field coil.
